The Indianapolis Colts quarterback was limited in Wednesday's practice due a sore right throwing shoulder, and injury suffered in Sunday's 35-33 win at Tennessee. Luck and head coach Chuck Pagano revealed the injury two days after giving assurances the quarterback didn't have any physical issues aside from normal bumps and bruises. Luck admitted he lied after the game about the injury.

He still expects to play Sunday when the Colts (1-2) host the Jacksonville Jaguars (1-2) at Lucas Oil Stadium. While Pagano said Luck is considered "day-to-day," the coach expressed optimism his three-time Pro Bowl quarterback would play.

"It didn't feel as good as I would have liked it to after the game," Luck said. "We'll take it day by day, and I expect to play, that's for sure. Obviously gonna defer to doctors and trainers and coaches on everything when it comes to that, but hopefully (I'll do) a little more (Thursday) and ready to go."

Pagano starts his press conferences with injury updates, but didn't mention Luck until the eighth player, perhaps another indication the team doesn't think it's serious.

Asked when he hurt the shoulder, if it was in the game and what play, Pagano said, "Pick one of 'em." Luck, who has been hit 21 times and taken five sacks in three games, said the injury happened Sunday.

"It's just sore," Pagano said, "so we err on the side of caution."

Speculation had swirled around Luck being injured, in part because he's thrown a league-high seven interceptions, and then there was the "wince" caught on camera during Sunday's game, when backup quarterback Matt Hasselbeck patted Luck on the chest on the sideline and Luck recoiled in obvious pain.

"To be, it's not that big a deal," Luck said, referring to the commonality of minor football injuries.

Hasselbeck said it's not the first time Luck has been asked to rest from practice, this is just the first time he decided to do it.

It's the first time he's been listed on the injury report since his rookie year in 2012.

Luck was obviously uncomfortable discussing the injury.

"It's part of it, I get it. It doesn't mean I have to enjoy talking about it to anybody," he said.
